Pirates of the Caribbean: On Stranger Tides

Pirates of the Caribbean: On Stranger Tides is an upcoming adventure film starring Johnny Depp, and the fourth film in the Pirates of the Caribbean film series. It is scheduled to be released in the US in Summer 2011.
As detailed in The Art of the Pirates of the Caribbean, the proposed story for the fourth film was for Sparrow and Barbossa to meet up in the newly founded New Orleans, before they sail to find the Fountain of Youth together. The story incorporates elements of the Tim Powers novel On Stranger Tides.
Johnny Depp signed on to return in September 2008, and Ted Elliott and Terry Rossio began writing under the guidance of producer Jerry Bruckheimer. The film is set for release in Summer 2011.
Geoffrey Rush has expressed interest in returning as Barbossa. Beforehand, Gore Verbinski was hesitant about directing, citing the incomplete scripts he worked with filming the sequels. Keira Knightley has stated that she does not wish to continue playing Elizabeth Swann because she wants to do different projects. Orlando Bloom has also stated that he does not wish to return.
In June 2009, Bruckheimer stated Disney would prefer the fourth installment of Pirates be released before The Lone Ranger film, which he, Depp, Elliott and Rossio had been working on for release in Summer 2011. He also hoped Verbinski would return to direct after his BioShock adaptation had been put on hold.
At San Diego Comic-Con 2009, Bruckheimer stated he intends to begin filming in April or May 2010. Rob Marshall entered negotiations to direct in August 2009.
Depp, in full Jack Sparrow get-up, appeared at the D23 Expo convention to announce the Summer 2011 release date and title as Pirates of the Caribbean: On Stranger Tides.
In September 2009, ¤¤¤¤ Cook, Chairman of Walt Disney Studios, resigned after holding his position for over 38 years. The circumstances of his resignation are unknown, but most speculate he resigned due to his conflicting business tactics with CEO Bob Iger. Iger sought out "new ways of doing business", while Cook remained a traditionalist. After Cook's resignation, Johnny Depp's faith in Pirates of the Caribbean: On Stranger Tides has somewhat shaken, with Depp explaining that "There’s a fissure, a crack in my enthusiasm at the moment. It was all born in that office". Depp also explained Cook was one of the few that accepted his portrayal of Captain Jack Sparrow, claiming that "When things went a little sideways on the first Pirates movie and others at the studio were less than enthusiastic about my interpretation of the character, ¤¤¤¤ was there from the first moment. He trusted me. Jerry Bruckheimer will be talking to Johnny Depp to try and convince him to stay with the Pirates of the Caribbean movie franchise, so that the future Pirates of the Caribbean movies can even happen at all."
